Indeed; though at the same time, based on new reports, he and Jor-el had their differences to the point where a fight scene took place between them on Krypton so Zod was no saint on Krypton during its prime that's for sure.

Well sure; Zod's a military leader, Jor-El's a scientist. It's a classic conflict, and I'm sure Zod was never exactly a peach, lol. But I'm also confident his motivations here will be more complex than just wanting to kill Jor-El's son or wanting a planet to rule. I mean, look at Battlestar Galactica (the re-imagining). Once their race was all but destroyed, the military faction of that ragtag bunch of remaining humans went straight into Hostile Mode toward anyone they encountered for pretty much the rest of the series. They became rather ruthless in the name of survival almost instantaneously. I could easily see a guy like Zod taking that kind of route as a leader (but to a much more extreme level since I'd imagine Zod was fairly ruthless to begin with).
